Classé Audio is a Canadian company that
makes only a handful of products, all of them high-end. They don't sell
entry-level components, unless you want to enter at high-performance. And that
is not a bad idea, because, although they are non-compromise quality, they are
not the most expensive products out there.

For example, the CDP-10 CD Player reviewed here, is beautifully constructed
and has fully differential DACs (one for the + and one for the - on each
channel), which delivers true balanced analog output, but is only $1,999.

Why no DVD-A or SACD?

In a world moving (slowly) towards CD, DVD-A, and SACD universal players, why
build a player that only handles CDs? Several reasons. One is that not
everyone is interested in DVD-A and SACD. CD is still a very good format, and
99.999% of the music out there is on CD. I read a recent survey that reported
almost half of the people surveyed said they were not going to buy DVD-A or
SACD players.

A second, and perhaps more important reason, is that a multi-player needs
additional circuitry to handle various formats, and those additional circuits
make noise even when they are not actively decoding one of the several
formats.

So, taking all of these concepts into account, there is still a market for
dedicated CD players, including high-end ones like the CDP-10.

Construction

The build quality of the CDP-10 is superb. The front panel fascia plate is
thick brushed aluminum, the LED readout is clear and legible, and the buttons
are simple. The rear panel has a main power toggle, and the front panel has a
standby button, which keeps the unit warm with trickle current when it is not
being used.

There are trigger sockets for communication with other components (so you can
turn everything on with one component), and the AC cord is grounded and
detachable.

The CDP-10 transport mechanism is one of the smoothest I have ever
experienced. That does not make it any faster or easier to load or unload
discs, but the smoothness of the tray handling implies that the disc is
handled more solid during playback as well.

The DACs

Not only are Burr-Brown 24/192 DACs used in the CDP-10, but a pair of them
(two stereo DACs). One is used for the positive leg and another for the
negative leg of each channel. This keeps the signal away from the ground plane
and provides for true balanced (XLR) output. The balanced output also gives
you more voltage (6 dB) along with common mode rejection of noise that gets
into the signal path along the way. Since my two-channel audio system includes
a fully balanced preamplifier (BAT VK-5i) and power amplifier (BAT VK-75SE), I
really looked forward to having a fully balanced source to go with them. As
you will see below, I wasn't disappointed.

You can use the CDP-10 as a transport, with the included coaxial digital
output jack if you like, but I found the audio section of the unit to be so
good, I would consider it a waste to bypass the analog outputs in favor of a
different DAC.

The Remote Control unit is brushed aluminum, and appears to have been routed
from a solid block of metal. You need a hex wrench to open the back and put in
the batteries. It is simple and elegant.

The Sound

Besides the BAT units I mentioned above, I tested the CDP-10 with Magneplanar
MG1.6/QR speakers, along with Nordost and BetterCables interconnects, and
Analysis Plus speaker cables.

What surprised me most, was that the CDP-10 had more detail than even SACDs
played on a mass market unit. I had really expected to find that SACD would
sound better than CD, regardless of the players. But no, the CDP-10 had more
substance. The leading edge of sounds was significantly clearer with the
CDP-10. And, even though the CDP-10 had more detail, the mass market SACD
player had more harshness. We are talking about two different things here
though, and it is probable that the quality of the support circuitry,
including op-amps at the output stage, are responsible for the sound
differences.

With full orchestra, I could delineate all instruments - i.e., no mushiness in
the midrange - and this suggested to me a low THD and IMD. Check out the
bench test results on this issue below.

All analog circuits of the CDP-10 are run in pure Class A bias. This can only
be done when a component has a large power supply, which the CDP-10 does have.
It made the CDP-10 warm during use, and my cat wanted to plop himself down
right on top of it. It is difficult to put into words exactly what Class A
does to the sound quality, but to me, I get a sense of greater smoothness and
speed (better attack on the leading edges of sounds).

The CDP-10 was also very, very quiet, which is probably due to the extremely
high quality power supply, with its multiple stages. The balanced output, with
its 6 dB additional signal, meant I did not have to turn up the volume control
on the preamp as much, and this gave me even more of a low noise background.

If you have read my previous reviews, you know I like chamber music, which
tends to be very easy to listen to, but that does not mean it isn't as
demanding as rock or popular music. In fact, the leading edges of piano and
violin are very difficult to reproduce. While listening to some Chopin, my
wife commented on the clarity of the CDP-10 and how the piano sounded like it
was actually in the room. She likes the convenience of a carousel CD player,
even though they are mostly mass market products, without the finesse of
high-end players, and when she requested that our CDs for the evening be put
into the CDP-10 instead, even though it meant getting up to change each disc,
I knew we had a great player here. This is the first time she has ever moved
away from the carousel player preference.

On the Bench

With a 1 kHz input signal from a test CD, THD was very, very low, at 0.00113%.
All bench tests were performed using the balanced XLR outputs.

At 10 kHz, THD was also very low. Notice also the noise floor. Compare that
with other CD players we have tested in the past, and you can see what fully
balanced delivers. The lack of any AC ripple in the 60 Hz region points out the value of a top notch power supply.
This is the kind of thing you are paying for in a high-performance component.

The IMD test, using a 10 kHz and 11 kHz input signal produced IMD so low, it
was beyond our test equipment's ability to detect it.

The frequency response is the only area I would like to have seen better
performance, as it begins rolling off at about 2 kHz to be 1.3 dB down at 20
kHz. This translates to 20 Hz - 20 kHz ± 0.65 dB. However, I want to point out
that there are many reasons for resulting non-flat frequency responses,
including not using a lot of negative feedback. My $4,500 preamplifier, which
uses no global negative feedback, is not very flat either, but, oh what a
sound!

Conclusions

CD is alive and well, and the Classé
CDP-10 sounds as good as any CD player I have ever heard. It is beautiful to
look at, and is priced reasonably. The CDP-10 is definitely a short list
inclusion for anyone shopping in the realm of dedicated CD components.
